Abstract

A computer allocation quantitative water distributor is a water distributor used for water distribution in oil field and oil well and aims to dissolve the shortcoming of the existing water distributor in the oilfield that the existing water distributor adjusts zonal water injection rate by replacing a water nozzle with mechanical drop-dipper method, which can not not only provide quantitative water distribution, but also completes one layer water distribution with multiple drop-dipper, with time-consuming effort and high cost as well as low water distribution accuracy; the computer allocation quantitative water distributor consists of a water distributor and a regulator, and the water distributor consists of a top joint, a blanking plug, a sealed section, a sealed ring and a lower joint; the regulator consists of a top joint, a computer control panel, a motor, a connecting section, a regulating joint, a joint, a drawbar, an insulation sleeve, a pressure cap, a contact, a contact point and a lower joint; the contact is contacted with the contact point to send a signal to the computer, and the computer controls the rotating of the motor to drive the regulating joint the rotate and to shift the blanking plug to rotate, thereby changing the water injection section, thus changing water injection rate and stopping water injection when scheduled water injection rate is achieved; the computer allocation quantitative water distributor has the advantages of quantitative water injection, time saving, energy-saving, low cost and high accuracy.

Description

Computer is allocated quantitative injection well downhole flow regulator

Technical field: the invention is employed water dispensing apparatus during water distribution in the oilfield; The invention is the improvement to the water dispensing apparatus structure, especially the improvement of adjustment and water structure.

Background technology: the present employed injection well downhole flow regulator of oilfield, all adopt mechanical pulling, change the way of water nozzle and adjust the seperated layer water injection amount, i.e. quantitatively water distribution, just can join one deck but also get repeatedly pulling, the cost height of not only wasting time and energy, and also the water distribution precision is low.

Summary of the invention: the purpose of the invention provides the computer of the quantitative water distribution of a kind of energy and allocates quantitative injection well downhole flow regulator; The purpose of the invention is achieved through the following technical solutions: computer is allocated quantitative injection well downhole flow regulator, is made up of injection well downhole flow regulator, adjuster; Injection well downhole flow regulator is made of top connection, blanking plug, seal section, joint ring, lower contact; Two sections internal thread through hole are made in top connection; Blanking plug is shaped on endoporus, and inner hole wall is made equally distributed tooth in the endoporus upper end, makes a spiral of Archimedes groove on outer wall, makes radial direction through hole at spiral of Archimedes groove beginning, destination county; Seal section is shaped on inner via hole, radial system one through hole, and the two ends external diameter is shaped on screw thread and closure gasket groove; Inner via hole is made in lower contact, makes internal thread in the inner via hole upper end, and external diameter is made external screw thread in the lower end; Joint ring is installed in the closure gasket groove on the seal section; Top connection, lower contact are screwedly mounted on the seal section two ends respectively, blanking plug is put are contained in the seal section inner via hole; Adjuster is made up of top connection, computer control panel, motor, linkage section, adjusting head, joint, pull bar, pressure cap, insulation sleeve, contact, contact, lower contact; Top connection is shaped on inner chamber and through hole, and the lower end is shaped on external screw thread; Linkage section is made tube-like piece, makes opening at the middle part; Regulate head and make eccentric cam; Joint is shaped on inner via hole and external screw thread and internal thread; Extension bar is made step external diameter and inner via hole; Pressure cap is shaped on inner via hole and external screw thread; Insulation sleeve is shaped on installs the contact nest, and inner chamber and contact nest are made in lower contact, and lumen port is shaped on internal thread, and internal thread hole is made in the lower end; With motor, the computer control panel is contained in the top connection inner chamber successively, motor shaft connects by the through hole in the top connection regulates head, and linkage section is screwedly mounted in the top connection, and joint is screwedly mounted on the linkage section, pressure cap is sleeved on the pull bar, pull bar is screwedly mounted on the joint, contact is installed on the insulation sleeve, insulation sleeve is installed in the inner via hole of pull bar, the contact is installed in the contact nest of lower contact, lower contact is screwedly mounted on the pressure cap.

The advantage of the invention: owing in adjuster, adopted computer, there is ground to set in advance the function of laminated distributor under well water distribution quantity, once go into the well and then the water injection rate of each layer of down-hole can be adjusted to the numerical value that ground sets in advance, simultaneously finish flow rate test at allocation process, can not allocate yet, single each layer water injection rate of surveying, the cost that not only saves time is low, and allotment is accurate, under the prerequisite of disregarding flow meter self error, the water distribution degree of accuracy can reach 100%, but this injection well downhole flow regulator also has the function of pulling, can change blanking plug when needs carry out testing seal about packer and survey static pressure or block certain layer; Owing to adopt the blanking plug that spiral of Archimedes groove structure is arranged in the injection well downhole flow regulator, rotated by computer commander motor, driven by motor is regulated head and is stirred in the injection well downhole flow regulator some in 16 teeth on the blanking plug, and blanking plug is rotated, changed the area of water injection hole, thereby changed water injection rate, be issued to predetermined water injection rate in the control of computer, motor has not just been worked, water injection rate has also just been harmonized, repeatedly pulling just can be finished one deck water distribution, therefore saves time, and reduces cost.
